Hi, if we already purchased the 7th guest, is it a free upgrade to the 25th anniversary?

Doesn't look like it, it's showing me a 66% off discount. When it means like 3 dollars to upgrade, if that's permanent, I'll consider it down the road a bit, however for a 25 year old game, I do kinda think the upgrade should be free to previous owners. Ah well, at least it's not twice the price of the original and no discount like I've seen others do.

This is somewhat related, what googdies were included in the original release of 7th Guest? Do they differ from the new release?

I still have the original on my account as well as the new version so here's a comparison:
Original release contains:
Manual
Script
Soundtrack
Making-of video
Avatar
Original Mac version of The 7th Guest

New release contains:
Manual
Script
Novel
Stauf Files
Soundtrack
Deleted Scenes (19)
Making Of Featurette
Avatar
Legacy Version (Windows)
Legacy Version (OSX)
Legacy Version (Linux)

So it looks like what you're getting in the new one are the "Stauf Files", Novel, and Deleted Scenes on top of the original game and extras.

Thnaks. That's good to hear. i feel we ususally get screwed on goodies when a game gets relisted.

I am a little disapointed honestly. Part of the charm of GOG is that they asure you that the games will work. I buyed this game and now I cant play and I need to pay more money to get the new version. I think that the owners of the game should get the new version for free or at least a refund for the old game that no longer works.
